In the Atlantic Ocean, rescue crews have called off a multinational, multimillion-dollar operation to locate five people aboard the missing Titan submersible after debris from the vehicle was discovered Thursday near the wreckage of the Titanic. Engineers say the sub’s operator, OceanGate, failed to properly account for design failures in the submersible, which was never certified to withstand the crushing pressures of the deep ocean. It’s believed the sub’s pilot, OceanGate CEO Stockton Rush, died instantly along with four passengers who paid $250,000 each for the adventure. This is Rush speaking in a 2022 documentary by Mexican filmmaker Alan Estrada.

Stockton Rush: “I’d like to be remembered as an innovator. I think it was General MacArthur who said, ’You’re remembered for the rules you break.’ And, you know, I’ve broken some rules to make this. I think I’ve broken them with logic and good engineering behind me. The carbon fiber and titanium, there’s a rule you don’t do that. Well, I did.”

The Wall Street Journal reports that a top-secret U.S. Navy acoustic detection system designed to spot enemy submarines heard what the U.S. Navy suspected was the Titan submersible implosion, just hours after it began its voyage.
